Description

BACKGROUND

Computer system workstations are ubiquitous in today's fast-paced and information-dependent society. Among the many components of traditional computer systems, an electronic-visual display, personal computer, and power source are the most prevalent and standard features of a functional workstation. As advances in technology and the demand for smaller systems increase, manufacturers have developed integrated work centers (IWC) that aid in providing a compact and integrated display and personal computer. These work centers are particularly useful for space-constrained and public computing environments. However, the power source associated with such systems is typically bulky and incompatible with the thin and robust design of the most integrated work centers.

DETAILED DESCRIPTION OF THE INVENTION

The following discussion is directed to various embodiments. Although one or more of these embodiments may be discussed in detail, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be an example of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment. Furthermore, as used herein, the designators “A”, “B” and “N” particularly with respect to the reference numerals in the drawings, indicate that a number of the particular feature so designated can be included with examples of the present disclosure. The designators can represent the same or different numbers of the particular features.

The figures herein follow a numbering convention in which the first digit or digits correspond to the drawing figure number and the remaining digits identify an element or component in the drawing. Similar elements or components between different figures may be identified by the user of similar digits. For example, 143 may reference element “43” in FIG. 1, and a similar element may be referenced as 243 in FIG. 2. Elements shown in the various figures herein can be added, exchanged, and/or eliminated so as to provide a number of additional examples of the present disclosure. In addition, the proportion and the relative scale of the elements provided in the figures are intended to illustrate the examples of the present disclosure, and should not be taken in a limiting sense.

Some integrated work centers/workstations include retro-fitted Velcro or similar adhesive straps for supporting the power supply. However, since the power supply is only supported at the few points where the Velcro strap or adhesive makes contact, this method fails to provide the requisite force and reliability for secure fastening. Other methods use a built-in casing for supporting an associated power supply. However, the presence of numerous cables coupled with the weight of the power supply often forces the casing open thus causing the power supply to slip and fall in many circumstances.

Examples of the present invention disclose a power supply containment device for a computing system. According to one embodiment, the power supply containment device includes a main housing and a clamp portion coupled to the main housing. The clamp portion is configured to extend perpendicularly from the main housing. Furthermore, rubber padding formed on facing surfaces of the clamp portion and main housing are used to securely hold a power supply module between the clamp portion and main housing of the containment device.

Referring now in more detail to the drawings in which like numerals identify corresponding parts throughout the views, FIG. 1 is a three-dimensional perspective view of an integrated workstation and power supply containment device according to an example of the present invention. As shown here, integrated workstation 100 includes an all-in-one computing device (i.e., display and processing unit) 102, a base stand 104, and a power supply containment device 105. The computing device 102 is attached to the base stand 104 so as to provide an upright viewing angle of the display to an operating user. According to one example, the power supply containment device 105 is affixed to a rear area 108 of the base stand 104 and includes a moveable clamp portion 110. Furthermore and as will be explained in further detail below with reference to additional figures, the moveable clamp portion 110 of the power supply containment device 105 is configured to assist in clamping a power supply module—used to power the computing device—within the containment device 105.

FIG. 2 is another three-dimensional perspective view of an integrated workstation and power supply containment device according to an example of the present invention. As shown in this example embodiment, a power supply containment device 210 is attached to rear area 208 (i.e., area opposite front area 207) of the base stand 204. The power supply module 220 is positioned within the containment device 205 via the clamp portion 210. Furthermore, the power supply module 220 includes cabling 211 coupled to the computing system 202 for providing power thereto. In one example, the containment device 205 includes cable management clip elements 212 for hiding and managing cabling 211 associated with the power supply module 220. As shown here, cabling 211 wraps around and through the clip elements 212. Additionally, upper positioning of the clip elements 212 on the containment device 205 allows the cables 211 of the power supply 220 to be dressed up and over the power supply 220 and main housing 209 of the containment device 205 so as to not interfere with the clamping means while also providing a more aesthetically pleasing design for the integrated workstation 200.

FIGS. 3A and 3B are three-dimensional views of the power supply containment device according to an example of the present invention. FIG. 3A depicts the power supply containment device 305 and clamp portion 310 in a closed or retracted position. More particularly, when in a closed position, the clamp portion 310 of the containment device 305 is immediately adjacent to the main housing 309 of the containment device. According to one example embodiment, a pair of

clip elements

312 a and 312 b are formed on a top surface 316 of the main housing 309 and are utilized to hold and route cables of the power supply module. As shown in FIG. 3B, a perimeter surface 313 of the main housing 309 includes a rubber pad 315 a for gripping a surface of the power supply module. Clamp portion 310 also includes a rubber pad 315 b formed on an inner surface 314 that is opposite and faces the perimeter surface 313 of the main housing 309. The clamp portion 310 extends perpendicularly away from the perimeter surface 313 of the main housing 309 when in placed in an open or clamping position (similar to a disk tray). As a result, a flat plane or gap area 317 is created between the perimeter surface 313 of the main housing 309 and the inner surface 314 of the clamp portion 310 for receiving the power supply module. Combined with rubber pad 315 a, the clamp portion 310 and rubber pad 315 b thereof serve to aid in securely positioning the power supply module within gap area 317 as will be described in greater detail with reference to FIGS. 4A-4C. Moreover, due to its compact design, the power supply containment device 305 may be added onto the many existing base stand configurations.

FIGS. 4A-4C are side views of the integrated workstation and power supply containment device according to an example of the present invention. As shown in FIG. 4A, the power supply containment device 405 is affixed to a rear area of the workstation and base stand 402. Here, the clamp portion 410 is in a closed or retracted position in which clamp portion 410 abuts the main housing 409 of the containment device 405. In one example, an adjustment mechanism 403 for the clamp portion 410 is positioned within the main housing 409 of the containment device 405. The adjustment mechanism 403 may be a spring-loaded clamp, adjustable clamp (manually adjustable by a user), latch, or similar mechanical mechanism that allows for protraction and retraction (e.g., paper tray movement) of the clamping portion 410 from/to the main housing 409 while also providing sufficient force to hold an item (i.e., power supply 420, FIGS. 4B-4C) in a fixed position when clamped between surfaces (i.e., inner surface 414, FIG. 4B, of clamping portion and perimeter surface 413, FIG. 4C, of main housing). In the present example, a spring-loaded clamp is represented as the adjustment mechanism 403. As shown here, the spring of the clamp 403 is in a normal extended position when the clamp portion 410 is in the closed position (i.e. adjacent to main housing). Moreover, a tab end 419 of the clamp portion 410 is attached to spring of the clamp 403 for providing the requisite movement of the clamp portion 410 as will be highlighted in the description of the figures below.

With respect to FIG. 4B, the clamp portion 410 is extended outward as indicated by the directional arrow so as to create a flat plane or gap area 417 between

surfaces

413 and 414 for placement/insertion of the power supply 420 (as indicated by downward directional arrow). In turn, the tab end 419 of the clamp portion 410 slides perpendicularly with respect to the perimeter surface 413 of the main housing 409 so as to cause the clamp spring 403 to contract as shown in FIG. 4B. As mentioned above,

rubber pads

415 a and 415 b are formed on a perimeter surface of the main housing 407 of the containment device 405 in addition to an inner surface 414 of the clamp portion 410 (i.e., surface opposite the perimeter surface 414 of the main housing 409) respectively. When the clamp portion 410 of the containment device 405 is positioned in an open or clamping position, the

rubber pads

415 a and 415 b are used to prevent the power supply 420 from slippage or lateral movement within the gap area 417 as shown in FIG. 4B. More particularly and according to one example embodiment, once the power supply 420 is positioned with the gap area 417, the clamp portion 410 may be released causing the clamping spring 403 to expand and the clamp portion 410 to retract back (indicated by directional arrow of FIG. 4C) towards the perimeter surface 413 of the main housing 409. Such movement ensures that sufficient force is placed on the

opposite contact sides

421 a and 421 b of the power supply module 420 by

rubber pads

415 a and 415 b of the main housing 409 and clamp portion 410 respectively.

Many advantages are afforded by the containment device of the present examples. Since the clamp portion is adjustable, it may be used with equal effectiveness for power supply modules of different sizes and shapes. Furthermore, the rubber pads of the containment device—in combination with the clamp portion—provide enough force and stability to hold the power supply in a fixed position. Cable management integration combined with the omission of the unsightly and seldom used Velcro straps of prior solutions serves to provide a more aesthetically-pleasing overall look of the workstation. Still further, the containment device may be added to existing integrated workstations with minor modifications thus reducing manufacturing costs while providing seamless integration.

Furthermore, while the invention has been described with respect to exemplary embodiments, one skilled in the art will recognize that numerous modifications are possible. For example, although exemplary embodiments depict an all-in-one computer as the representative computing device, the invention is not limited thereto. For example, the computing device of the workstation may be a television monitor, a notebook computer, a tablet personal computing device, or any other electronic device and workstation having a base stand, supporting structure, or power supply.

Furthermore, the power supply containment device may be positioned at any location with respect to the base stand or workstation. For example, the containment device may be attached to the side or front area of the workstation and base stand. Similarly, the containment device and clamp portion can be formed in varying sizes and shapes rather than those depicted in the figures. Still further, the clamp portion may extend in any direction (e.g., vertically) with respect to the main housing so as to still provide a secure clamping means for the power supply module. Thus, although the invention has been described with respect to exemplary embodiments, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
